Which one of the following climatic types (Köppen's Scheme) is best suited to describe the climate of the western fringe of Rajasthan ?
- A.Amw
- B.Aw
- C.BWhw
- D.Cwg
Correct answer
Explanation
The correct answer is C, BWhw. In Köppen's scheme it stands for a hot desert climate with its little rain in summer, which fits western Rajasthan.
Köppen used capital letters for the main groups: A tropical, B dry, C warm temperate. In the B group, W means desert (as against S for steppe), h means hot, with a mean annual temperature above 18°C, and the last w here marks the scanty rain that comes in the monsoon season. The Thar desert in the extreme west of Rajasthan, around Jaisalmer and Barmer, gets less than 15 cm of rain a year and has very hot summers, so it is classed BWhw. The semi-arid belt just east of it is BShw.
A, Amw, is the monsoon type with a short dry season, found on the Konkan and Malabar coasts. B, Aw, is tropical savanna, covering most of the peninsular plateau. D, Cwg, is the monsoon type with dry winters, found over much of the Ganga plain.
Exam tip: B = dry, W = desert, h = hot; BWhw = western Rajasthan, BShw = its semi-arid fringe.
